07' XB9R - Low oil pressure, won't stay running, grinding noise when key turned to ON

[ksva]

Hi all,

My XB left me out on the side of the road today. She is a 2007 XB9R. Was wondering if anyone might know what happened:

Coming up to a stop light and the bike dies, I look down and see the oil pressure light on. I pull her off to the side of the road to check oil level. Oil level is fine, and looks acceptable. (Just a note: the oil has less than 500 miles, it is Mobil 1 Syn).

I turn the key back to 'on' and the low oil pressure light is gone. Strange. I ride down the block to take her home, and after a mile or two the light comes back on. Started loosing power so I immediately shut her down and pulled over. Finally I got her on to a flat bed and she's resting in the garage.

Recap
-Oil pressure light comes on
-Grinding/Strange noise when pumps prime (flipping key to ON)
-Bike would not stay running
-Ecmspy reports no error codes (or I am doing it wrong...)

I have read really bad things about this 'oil pump drive gear'- things like it taking other engine parts out when it does go. Does this sound like the symptoms of a bad oil pump?

Thoughts?

Oil pump drive gear upgrade was standard on 06+ xb's. Grinding noise is the fuel pump. Are you sure it was the oil pressure light and not the check engine light?

Oh and by the way.... The first time when the bike died at a light the oil pressure light was on cause there was no oil pressure since the bike wasn't running.

I am still learning- but I am pretty sure it was the oil light.

I should have explained better, the oil light stays on even when the engine is running. When it started to sputter at the stop light I looked down and saw the oil light on. The check engine light never came on while in operation.

I just ran the fuel pump test in ECMSpy, it sounds really bad. Sounds like you are spinning an RC car wheel really slow.

So I guess I am dealing with a bad fuel pump, and something else?

Also- not sure if it helps but the bike has 18k mi on it.

I girl you know you need a pump at the very least. What's odd to me is that you said you restarted it and the light went out. Usually when you have a oil pump failure it just quits.

If your 07 has not had the regulator-connection upgrade, then it could be symptoms of your regulator crapping out. The 08's had the regulator-connections replaced with a round pin style, from a flat-pin style. To handle more voltage output. When my 07 regulator went out, all the same symptoms were there. Also, if your bike is for some reason being leaned way over the lean-angle degree (like close to on its side) then it will register a pressure malfunction from the engine. I took off the oil filter and put it back on and my oil light went off.

Interesting. I have had weird issues with my headlights this past week as well (not coming on instantly). When fiddling with that issue I checked voltage through ecmspy, which was solid. I figured that the ballast I have for the HID was beginning to fail and swapped it out. Maybe this is related?

I did not have the bike leaned over any further than what would happen during normal riding. I'm still confused as to why that light is on.

Sounds like I will have to replace the fuel pump and go from there-
